I met 2 invisible men's in fluorescens suits. I ask: "Who are you??". They answer: "Don't worry about us, we are only living in your mind and we cleaning here". "In my brain? It's so many spacr here??". And they said "Hehe:) look. Over there! And wait when we finish cleaning then you will see..." So I look over there and I was in the darkness on the beach and univers was reflected on the water.... I couldn't believe this huge universe is in my brain.
